<p>This plugin allows you to take control over the execution of cron jobs. It’s mainly useful for sites that either don’t get enough comments to ensure a frequent execution of wp-cron or for sites where the execution of cron via regular methods can cause race conditions resulting in multiple execution of wp-cron at the same time. It can also help when you run into posts that missed their schedule.</p>
<p>This plugin implements a secret parameter and ensures that cron jobs are only executed when this parameter is existing.</p>
<h3>Limitations</h3>
<p>This plugin performs a <code>remove_action( 'sanitize_comment_cookies', 'wp_cron' );</code> call in order to disable the spawning of new cron processes via the regular WordPress method. If <code>wp_cron</code> is hooked in an other action or called directly this might cause trouble.</p>
